Summary
👤
Senior🎓
Top SchoolKristjan Roosild is a Senior Software Engineer with 11 years of hands-on experience shipping product-focused systems across fintech and startup ecosystems in APAC, Brazil and the EU. He blends backend engineering, streaming architectures and NLP/ML — from building Kafka stream processors and microservices at Wise to creating production-grade natural language search and classification models at ZUMATA and Hoorah!. Based in Tallinn, he is completing a master’s in Data Science and is deliberately transitioning toward full-time machine learning and data science roles while still solving scaling and compliance problems for global money movement. Notably, he has repeatedly taken sole-ownership of mission-critical projects (from a GIS portal rolled out across Bahia to AML tooling and adverse-media pipelines), demonstrating a mix of product sense, rapid prototyping and operational rigor.
